Abstract: PURPOSE: To improve the impregnating property of the insulated layer formed by winding a plastic tape including polyolefin or a compound tape made of this material and a kraft paper around a conductuve material through impregnation of diarly alkane with a specified viscosity.  
     CONSTITUTION: An insulated layer formed by winding a plastic tape such as polyolefin, polycarbonate, polyester, and polyethylene tetrafluoride and a compound tape made of this material and a kraft paper around a conductive material is impregnated with a diaryl alkanic hydrocarbon with a viscosity of less than 23c St at 30°C. For the diarly alkane, applicable is 2, 3 diphenyl isopentane and 1, 6 d iphenyl isooctane, for instance. For the plastic tape, ideal is a biaxial drawn polypropylene with a thickness of 50 to 100μ, for instance. With such an arrangement, less resistance of oil flow improves the impregnating property thereby reducing change in the oil pressure associated with a load variation. In this manner, cable excellent in the insulation property can be produced

IPC: H04B10/60
Filed: 1988-05-23
Abstract: PURPOSE:To improve crosstalk characteristics with simple constitution by propagating a signal which is inputted to a filter element reciprocally in the element. CONSTITUTION:A Mach-Zehnder interferometer consists of optical demultiplexers 1-1 and 1-2 and optical waveguides 2 and 3 which couple those optical demultiplexers and an optical isolator 4 is coupled between a port C and a port D. At this time, the light signal which is inputted to a port A and outputted from a port B passes twice through the Mach-Zehnder interferometer which has exactly the same characteristics (from the port A to the port C and from the port D to the port B). Consequently, the two ports are only connected by using the element which propagates the signal only in one direction to improve the crosstalk characteristics.

Abstract: PURPOSE:To eliminate the phase displacement of projecting beams and a reflecting mirror, and to realize a semiconductor laser light-source conducting stable single transverse mode oscillation by using a phase conjugate mirror as an external mirror. CONSTITUTION:A barium titanate group phase conjugate mirror 11 is used in place of a reflecting mirror, one part 12 of outputted beams 6 is divided by a beam splitter 13, and introduced to the phase conjugate mirror 11 by a reflecting mirror 14, an optical isolator 15 and a reflecting mirror 16 and functions as one excited beams, and beams transmitted through the conjugate mirror 11 progress in the opposite direction by a reflecting mirror 17, and serve as the other excited beams.

Abstract: PROBLEM TO BE SOLVED: To prevent flocks from flowing out by simple facility and make soluble substances even by installing flow rectifying plates in an immersed-in-water part of an arm to which a scraper of a precipitated sludge scraping apparatus is attached to be supported. SOLUTION: In the center part of a horizontal flow type precipitation tank 1 in the longitudinal direction, the flow speed of wastewater in the up and down direction in the precipitation tank 1 is measured by a flow meter such as a blade rotation type flow meter. Based on the result of measurement, the flow speed of wastewater in the precipitation tank 1 in the up and down direction is made to be even. That is, either an arm 7b of a scraping apparatus 7 or flow rectifying plates 10a, 10b, 10c, 10d themselves whose width direction is faced to the wastewater flow direction fL are inclined or rotated to adjust the angle of the respective flow rectifying plates 10a, 10b, 10c, 10d to the horizontal face.  Consequently, these flow rectifying plates can response to alteration of treatment conditions such as alteration of flow speed distribution in the precipitation tank and flocs are prevented from flowing out by the simple facility and soluble substances are made even.

Filed: 1982-07-23
Abstract: PURPOSE:To increase the starting torque without loss of characteristics such as high efficiency, high power factor and the like by respectively inserting a positive temperature coefficient thermistor and an AC voltage phase control element into auxiliary coil and main coil circuits. CONSTITUTION:Since the temperature of a positive temperature coefficient thermistor 14 which is inserted into an auxiliary circuit at the starting time is low, the impedance of the auxiliary circuit is low, and a large auxiliary coil current is flowed. An AC voltage phase control element 11 which is inserted in series with the main coil circuit is controlled so that the current at the starting time does not excessively increase and so as to obtain sufficient starting torque. When the starting operation is completed, the thermistor 14 is raised at the temperature due to the self-heating. Accordingly, its resistance is varied from low to high value, and a motor is efficiently operated as a capacitor motor.

IPC: G11B11/10
Filed: 1989-05-22
Abstract: PURPOSE:To attain the overwrite with the reduced miserasion and jitter by using two beams for erasing and recording pulses. CONSTITUTION:A recording laser pulse is produced from an information signal via a recording laser driving circuit 1 and a laser diode 3, and an erasing laser pulse is produced from an erasion signal via an erasing laser driving circuit 2 and a laser diode 4. These laser pulses are condensed on a disk 7 via a beam splitter 5 and a superposed objective lens 6. In this case, the condensing points of both recording and erasing laser pulses are set on the same track and the erasion beam precedes the record beam in terms of the disk revolving direction. The recording and erasing magnetic fields are applied by a single permanent magnet 8. Thus it is possible to obtain the satisfactory overwrite characteristic which produces no miserasion nor jitter of the recorded data.
